Always wrong collision model when compiling.

Garry's Mod modelling
#1

Hello!

I made a static prop for Garry’s Mod so I obviously made a collision model for it,
but after compiling the model, for an unknown reason, Crowbar Compiler decides to change the collision model to something else:

Before compiling :

424×820 35.2 KB

After compiling :

391×810 41.8 KB

Could somebody help me please?

Thanks!
